Mexico's earliest major civilization, on the Gulf Coast, famous for its colossal carved stone heads.
See it on the History map →What happened
The Olmec lived in the hot, swampy lowlands of today's Veracruz and Tabasco. Centers such as San Lorenzo (about 1200–900 BC) and La Venta (about 900–400 BC) had earthen pyramids, plazas and stone drains. Sculptors carved 17 known colossal heads, probably portraits of rulers, from basalt boulders weighing up to roughly 40 tonnes, moved from mountains dozens of kilometers away. They traded jade and obsidian widely and played a ballgame with rubber balls; 'Olmec' is an Aztec word meaning 'rubber people'.
Why it matters
Often called Mesoamerica's 'mother culture', it helped spread pyramids, the ballgame, jaguar imagery and possibly the calendars and writing later used by the Maya and Aztecs.
How we know
Excavations at San Lorenzo and La Venta since the 1940s; the colossal heads; radiocarbon dates; ancient rubber balls preserved in a bog at El Manatí.
Still debated
Scholars debate whether the Olmec were a 'mother culture' or one of several 'sister cultures'; their own name for themselves is unknown.

▸Maize domesticated in Mexico fed Olmec civilizationWell documented
The connection
Maize (corn), domesticated from a wild grass called teosinte, took thousands of years to grow large cobs. By about 1500 BC, with beans and squash, it could feed settled villages. The Olmec grew it on fertile river floodplains, and its surpluses supported the laborers, craftsmen and rulers who built their ceremonial centers.
When and how
Southern Mexico: maize was domesticated in the Balsas River valley about 7000 BC; the Olmec heartland in Veracruz and Tabasco flourished from about 1200 BC.
How we know
Maize pollen, cobs and starch grains in Olmec-area sediments; chemical traces in human bones showing maize-rich diets; Olmec carvings of a maize god.
Debates and open questions
How much the earliest Olmec relied on maize versus fish, root crops and wild foods is debated; maize's share of the diet seems to have grown over time.
▸Olmec civilization influenced Classic Maya civilizationMostly agreed
The connection
The Olmec of Mexico's Gulf Coast, often called Mesoamerica's 'mother culture', pioneered features later central to Maya life: ceremonial centers with earthen pyramids, a sacred ballgame, rulers shown as semi-divine, and probably early calendar ideas. These spread through trade networks, and early Maya sites absorbed them many centuries before the Classic period.
When and how
Gulf Coast centers such as San Lorenzo and La Venta, c. 1200–400 BC, in contact with early Maya sites like Ceibal and, later, El Mirador.
How sure are we?
Shared art styles, traded jade and similar site layouts. At Ceibal, Guatemala, a ceremonial plaza dated about 1000 BC follows a pattern also seen at Olmec sites.
Debates and open questions
Whether the Olmec were a 'mother culture' or one of several 'sister cultures' trading ideas is a long debate; Ceibal's plaza may even predate La Venta's.
▸Olmec civilization began traditions inherited by Aztec EmpireMostly agreed
The connection
The Olmec of Mexico's Gulf Coast set patterns that later Mesoamerican peoples, including the Aztecs, shared: pyramid-temple centers, a ritual ballgame played with rubber balls, jaguar and serpent imagery, and calendar-keeping. Over 2,000 years later the Aztecs collected Olmec carvings as sacred relics and buried some in offerings at their Templo Mayor.
When and how
Gulf Coast of Mexico, about 1200–400 BC, at San Lorenzo and La Venta; the Aztecs in central Mexico, 1300s–1521.
How sure are we?
Shared art, architecture and ballcourts across Mesoamerican sites, and Olmec greenstone objects excavated from Aztec offerings at the Templo Mayor.
Debates and open questions
Scholars debate whether the Olmec were a 'mother culture' for all Mesoamerica or one of several 'sister cultures' that influenced each other.
